What it brought

Model Context Protocol shows up across the stack. A Salesforce-hosted MCP server entered beta so AI assistants can reach org data securely, and the Salesforce DX MCP Server and LWC MCP Tools betas take the same idea into the IDE. Agentforce gained a new Agentforce Builder and Agent Script, a language that combines deterministic steps with LLM reasoning, both in beta. Data Cloud was rebranded Data 360, and SLDS 2 reached GA. One for the diary: the SOAP API login() call in versions 31.0 through 64.0 retires in Summer '27.
